A retractable in-line inking/coating apparatus selectively applies either spot or overall ink/coating to a blanket or flexographic plate on a blanket cylinder or spot coating or overall ink/coating to a flexographic printing plate on a plate cylinder in a rotary offset printing press. The inking/coating apparatus is pivotally mounted on the tower of a printing unit or dedicated coating unit, and is extended into and retracted out of inking/coating engagement by a carriage assembly which is pivotally coupled to the printing unit tower. Because of the pivotal support provided by a cantilevered support arm, the inking/coating apparatus can be raised and lowered through a Ferris wheel arc movement between adjacent printing units. The aqueous component of the printing ink or coating is evaporated by a high velocity, hot air interstation dryer and a high performance heat and moisture extractor so that the ink on a freshly printed sheet is dry before the sheet is printed on the next printing unit. Thus, flexographic ink or coating applied at the first printing unit can immediately be overprinted on subsequent printing units.

A retractable in-line inking/coating apparatus can apply either spot or overall inking/coating material to a plate and/or a blanket on the first printing unit or on any consecutive printing unit of any rotary offset printing press. The inking/coating apparatus is pivotally mounted within the conventional dampener space of any lithographic printing unit. The aqueous component of the flexographic printing ink or aqueous coating material is evaporated and dried by high velocity, hot air dryers and high performance heat and moisture extractors so that the aqueous or flexographic ink or coating material on a freshly printed or coated sheet is dry and can be dry-trapped on the next printing unit. The inking/coating apparatus includes dual cradles that support first and second applicator rollers so that the inking/coating apparatus can apply a double bump of aqueous/flexographic or UV-curable printing ink or coating material to a plate on the plate cylinder, while simultaneously applying aqueous, flexographic or UV-curable printing ink or coating material to a plate or a blanket on the blanket cylinder, and thereafter onto a sheet as the sheet is transferred through the nip between the blanket cylinder and the impression cylinder. A triple bump is printed or coated on the last printing unit with the aid of an impression cylinder inking/coating unit.

cDNA clones coding for the chicken cysteine proteinase inhibitor cystatin were found and isolated using for example a synthetic oligonucleotide probe corresponding to amino acids 81-90 of the cystatin sequence. This was used to screen a lambda gt 11 chicken oviduct cDNA library. A full length cystatin cDNA was also isolated.
